We have observed conductance fluctuations due to electron interference in a split-gate quantum dot, fabricated in the two-dimensional electron gas of a GaAs/Al x Ga 1-x As heterojunction. We have determined the phase breaking time of electrons by two independent analyses, using the correlation field
